The Cuban American peeled off on film for the first time for the scene in WE OWN THE NIGHT.

Speaking at the Cannes Film Festival, 33-year-old Mendes says, "I wasn't comfortable at all.

"They were very sweet and they poured me a vodka and orange juice and then I was fine,

"I'm very professional and I don't usually drink on the job but that morning I had a little vodka and OJ."
